Definitions

• the invention relates to a device according to the preamble of independent patent claim 1.
• a device of this type has become known in the prior art from DE-A-28 20 957. Such a device can be used, for example, to increase the performance when processing a stream of shingles arriving from a rotary printing press. However, it can also be used for eliminating faulty printed copies, or for sorting, etc. It has now been shown that an exact separation of individual printed products is not reliably possible with this device. This device has therefore not been used in practice.
• the task is solved in a device according to the invention in that when the carriage is moved away from the step, the conveying speed of the second conveying path is increased. By increasing the speed, a printed product removed from the stream of shingles is moved away from the step in a shorter way and at the same time faster. By increasing the conveying speed in the area of the second conveying line, a negative passing on is also avoided. It has also been shown that the increase in the speed mentioned by means of a mechanical clutch is very reliable and can be implemented in a structurally simple manner. The invention therefore allows the production of a device in which a complex control of the drive of the second conveyor line is avoided.
• the width of the second conveyor section has a receiving opening which can be adjusted at the front end. This makes it possible to adapt the receiving opening to the thickness of the printed products to be discharged. If the receiving opening is only closed when the leading edge of the printed product to be ejected has already been introduced into the receiving opening, this has the essential advantage that printed products, each consisting of several sections, are not torn apart and are safely ejected . Comprehensive printed products consisting of several sections can thus be discharged much faster than before and in a shorter way. Removal is possible with the device according to the invention over a shorter distance than before.
• FIG. 3 is a view of individual, exploded parts of the device according to the invention.
• FIG. 2 shows a first conveyor section 1 with two conveyor belts 3 and 4, which have a step S for fanning out a scale flow 28.
• the conveyor section 1 transports the scale flow 28 over the stage S from left to right, above the end of the conveyor in FIG. band 3 is arranged at a distance from the scale flow a known counting head 7, with which the printed products are counted individually and with which the positions of the printed products can also be determined.
• the counting head 7 is fastened to a machine frame 5, for example.
• a second conveyor section 2 begins above stage S and leads obliquely upwards from it.
• This second conveyor section 2 has a carriage 6 which is displaceably adjustable on a guide rod 12 between stops 14 and 15.
• a double-acting cylinder-piston unit 9 is provided, which is attached at one end to the machine frame 5 by means of a joint 8 and which is also attached to a bearing 13 of the slide 6 at the other end by means of a joint 10 is appropriate.
• Fig. 1 the lower end position of the carriage 6 is shown. From this, the carriage 6 can thus be moved upwards in the direction of the guide rod 12.
• a flap 16 is pivotally mounted on bearing plates 11 of the carriage.
• an arm 38 is attached to the side of the flap 16, to which a double-acting cylinder piston unit, not shown here, is attached, with which the flap can be pivoted upwards and downwards, starting from the position shown in FIG. 2 is.
• the flap 16 On the swivel axis 37 the flap 16 has a roller 25 mounted in the center. This roller 25, which is fixed with respect to the carriage 6, together with a clamping roller 23 mounted above it, forms a receiving opening A through which a printed product 28a (FIG. 4) to be discharged can be introduced between two sliding plates 26 and 27 of the second conveyor section 2.
• the pinch roller 23 is mounted on a toggle lever 22 which can be pivoted about an axis 18 by means of a double-acting cylinder / piston unit 20.
• the unit 20 is fastened to a bearing plate 11 of the slide by means of an articulated connection 21 and engages an articulation 19 on an arm 43 of the lever 17.
• the clamping roller 23 mounted on the other arm 22 can be lifted upwards from the roller 25, starting from the position shown in FIG. 2.
• the unit 20 can exert a contact pressure against the roller 25.
• the bearing 18 of the toggle lever 17 is again arranged in the center of a shaft 32 which is rotatably supported at its ends on the bearing plates 11 of the slide 6.
• one end of the shaft 32 projects through a bearing 33 and is connected at this end in a rotationally fixed manner to a gearwheel 34 which meshes with a toothed belt 28 on the inside.
• This belt 28 is guided over rollers 29 and 30, one roller 29 being fastened to a drive shaft 35.
• Both rollers 29 and 30 are mounted on the machine frame 5 at a distance from one another.
• Another endless drive belt 44 connects a roller 45 seated firmly on the shaft 32 to a roller 46 which is connected to the pinch roller 23.
• a pressure roller 29 is provided which is mounted on a bearing plate 1.
• a drive motor 45 is connected to the shaft 35 in order to rotate the pinch roller 23 in the direction of the arrow 41 regardless of the position of the slide 6. If the slide 6 is moved upward in the direction of the arrow 42 by means of the cylinder-piston unit, the gearwheel 34 experiences an additional drive due to the engagement with the toothed belt 28 as a result of this sliding movement.
• the rotational speed of the roller 23 is automatically increased in accordance with the speed of movement of the carriage 6 while the toothed belt 28 remains at the same speed. If, on the other hand, the carriage 6 is moved in the opposite direction of the arrow 42, the rotational speed of the pinch roller 23 slows accordingly.
• the flap 16 is pivoted into a lower “position, in that its front end engages the scale stream 28.
• a printed product 28a to be discharged is received by the flap 16 and is located with a leading edge K in the receiving opening between the roller 25 and the clamping roller 23.
• the toggle lever 17 is set by means of a cylinder-piston unit 20 such that there is a distance D between the rollers 25 and 23. This distance D is selected such that the printed product 28a is inserted between these two rollers without substantial resistance.
• the pinch roller 23 rotates in the direction of arrow 41 and can capture the printed product 28a with a preselected contact pressure.
• the toggle lever 17 is pivoted in the direction of the arrow 40 by means of the unit 20 and the contact pressure of the rollers 23 and 25 on the printed product 28a is increased.
• the carriage 6 is displaced by means of the cylinder-piston unit 9 in the direction of arrow 42 away from step S to the top right.
• the rotational speed of the roller 41 is increased as a result of this displacement.
• the retraction speed of the carriage 6 is, for example, 2 m / sec.
• the peripheral speed of the pinch roller 23 is thereby, for example. of 1 m / sec. at 3 m / sec. elevated.
• the speed of the belt 28 does not have to be changed here.
• the pressure product 28a clamped between the rollers 25 and 23 is thus pulled into the receiving opening A at an increased speed when the carriage 6 is pushed back. According to the increase in speed, the displacement because the time of the printed product 28a between the rollers 25 and 23 is correspondingly shorter. In addition, the printed product 28a is discharged from the scale stream 28 in a shorter time.
• the discharged printed product 28a is brought through the guide plates 26 and 27, for example, onto a further conveyor belt 48 or thrown into a container (not shown here).
• the carriage 6 can now be held in the waiting position in the position shown in FIG. 4 until another printed product is discharged, or it can be moved immediately into the starting position.
